红帽全球峰会2.7. 使用 yum在 RHEL 上安装多个次版本的 Red Hat build of OpenJDK
您可以在 RHEL 上安装 Red Hat build of OpenJDK 的多个次版本。这可以通过防止安装的次版本被更新。
先决条件
- 从非交互地选择系统范围的红帽 OpenJDK 版本，在 RHEL 上选择 OpenJDK 版本的系统范围版本。
流程
在
/etc/yum.conf目录中添加installonlypkgs选项，以指定yum可安装的 OpenJDK 软件包的红帽构建，但不更新。installonlypkgs=java-<version>--openjdk,java-<version>--openjdk-headless,java-<version>--openjdk-devel更新将在系统中保留旧版本时安装新软件包。
注意
Red Hat build of OpenJDK 的不同次版本可在 /usr/lib/jvm/ <minor version> 文件中找到。
